I haven't ran anything. I just want to increase my sex drive. Is .25mg once a week ok? I know twice than that is usually the norm but I think less would be ok?

Have you tried a natural test booster or some daa? I think caber probably isn't the best idea considering you won't be using it to combat prolactin. It's potent stuff brother, if I were you I'd look into some daa. Just my opinion though.
